Speeication forming part of Letters Patent No. lgt, dated September 1G, 1873; application le February 11, 1573. f

` To all whom it may concern:

Be it known that I, MARTIN F'. WES'SMANN, of Breokiyn, in the county of Kings and State of New York, have invented an lznn proved rlelegraph Receivinginstrument; and I do hereby declare that the following is a full and exact description thereof, .reference being had to the accompanyingdrawing, representing a longitudinal vertical seetion of a- 'telegraph receivinginstrn'ment provided with my improvements.

My invention consists, rst, in a brake or stop attached to orconnectedavith the armature of the marking or printing magnet, the said brake or stop being so. arranged that when-the magnet-circuit is brokenit holdsA the paper strip from winding oli', and releases it'wlien the .circuit is closed to mark or print thereon; second, in a swinging arm, or its equivalent, which presses upon the paper strip 'While the marking or printing magnet is in operation, and keeps it depressed or turned 'somewhat out of Vline b'ack` ofthe point 'of marking or printing; but when the marking or printing mechanism is stopped or interinitted for a seconder two, the 'clock or other movement which feeds the paper through the machine lifts the said arm, straightens the strip of paper, and lthereby produces the spacing between thewords.

The drawing represents a Morse or equivalent sign-marking instrument for receiving messages by electro-magnetic telegraph, A

being the paper strip; 'B B, the paperfeeding rollers, set in motion by suitable gearing operated by a weight, or its equivalent; U, the marking or printing electro-magnet; l), its armature; and E, the marking or print-- ing lever. The brake or stop G, which,'witl1 its adjuncts, constitutes the'lirst feature of my invention, as represented in the drawing, is adjustably attached to a rod, u., secured to the marking or printing lever E at a suitable distance from the' armature D to give the brake the required extent of move ment for accomplishing'its purpose. It is raised by a counterf sprin 3*, b, or its equivalent, and holds the paper strip A, when raised, by pressing it against a stationary' counter-surface, c. Thus, "when the marking tion for the purpose, and a bar or plate,f, at

its vibratory end presses on the paper strip A. 1t has a weight, g, or its equivalent, to

press it downward with.- the required force? to depress thev paper strip ont of the line ot its motion, as shown by full lines in the drawing, a stop, z, limiting its yibratory mcvement. Either the vposition of the pivot d is made adjustable, as shown in the drawing, by means of the disk i and set-screw Z, or the stop h is adjustable. The force of the Weight g is adjustable by varying its position, as indicated, by the suspending-holes m m, so that it will depress the paper istrip wlieirthe marking or printing lever is in motion by drawing "the paper strip over the [brake as it is momentarily released by the magnet; but as soon as the printing movement of the said marking or printing lever is stopped and the brake G brought against lthe paper strip, holding it from being drawn along, the force of the paper-feeding movement is sullicient to lift the arm Il against Athe force of its weight or spring, and to straighten the paper strip, as shown by dotted lines. This straightening oi' the paper strip is'suilicient to produce the requiredA spacing between the words.

'lhis invention is applicable to all telegraph-instruments in which the paper is iesi along by axnovement separate from the mai-le ing or printing mechanism, and also to allM kinds of eletro-magneticsignal-instruments which work on the saine principle, as for railA road-signals,.lire-alarms, &c.

That I claim as my invention, and desire to secure by Letters latent, is,-

1. A brake or stop, (l, attached to or, op.
